Greetings, Jacqueline!
Welcome to the Disney Parks Moms Panel. I can't wait for you and your granddaughter to make magical memories together at the Happiest Place on Earth. Currently at the Disneyland Resort,
any object that is pulled by a person, including wagons, are not prohibited at the theme parks. You are more than welcome to bring your own stroller or
rent one directly from the Disneyland Resort. These are rented and charged on a per day basis near the entrance of Disneyland Park.
Since you said your granddaughter has Autism, I wanted to inform you of some other services offered to
Guests with Cognitive Disabilities. To avoid standing in ticket lines, I recommend purchasing your
theme park tickets online. If your little one cannot tolerate extended wait times in line, she may be eligible for Disneyland's
Disability Access Service. This allows Guests to schedule a return time for an attraction based on the current wait time. Head to Guest Relations in Disneyland Park to see if you can utilize this service. Disneyland Resort is very accommodating, and I know you will have a magical experience no matter what.
I hope this helps, and feel free to return with any other questions.
-Jennifer
